ReportBuilderContext.DataSources property

Fuentes de datos utilizadas para crear el informe.

public Dictionary<object, string> DataSources { get; }

Observaciones

La clave representa la fuente de datos, mientras que el valor es el nombre de la fuente de datos. El nombre de la fuente de datos puede ser nulo o una cadena vacía; en tales casos, el motor de informes detectará automáticamente el nombre de la fuente de datos de la fuente de datos especificada.

Ejemplos

Muestra cómo rellenar un documento con fuentes de datos utilizando documentos de la secuencia.

// Hay varias formas de rellenar un documento con fuentes de datos utilizando documentos de la secuencia:
MessageTestClass sender = new MessageTestClass("LINQ Reporting Engine", "Hello World");

using (FileStream streamIn = new FileStream(MyDir + "Report building.docx", FileMode.Open, FileAccess.Read))
{
    using (FileStream streamOut = new FileStream(ArtifactsDir + "LowCode.BuildReportDataSourceStream.1.docx", FileMode.Create, FileAccess.ReadWrite))
        ReportBuilder.BuildReport(streamIn, streamOut, SaveFormat.Docx, new object[] { sender }, new[] { "s" });
